Versi tweeted that HTC has finished testing has been completed on the unlocked HTC One M8 and the update will begin pushing out within 24 hours. The Marshmallow update brings several improvements to the One M8 like Doze and Permission controls.

One of the features includes Doze, enhanced permission controls, etc. One of the better things about the Marshmallow update is that it gives users more privacy as it gives them control as to what apps they would like to give permission to access their personal information. Also Doze feature allows users to control their battery. Users can go to settings and manually check for updates or otherwise they can wait until they receive a notification for update.
